So the moderator emailed me back and said that the work is their own and I can’t use their worksheets but suggested those who are interested should join the group.
I would recommend joining this online group! It’s free – these people are like angels, doing this simply to help people wanting to learn the skills. You have to request access and explain that you’re committed to doing the weekly homework (and then actually commit to that) but they give you personalised feedback which you can review and reflect on so it is worthwhile.
The link for anyone who’s interested:
